Description
Technical field
The present invention relates to high power led electro light sources technical field, particularly relate to a kind of great power LED electric light source of Miniature low-noise active heat removal.
Background technology
Traditional electrical light source incandescent lamp utilizes heat radiation luminous, and because only the sub-fraction of filament institute consuming electric power being converted into visible ray, therefore luminous efficiency is low.From Government Of Australia at the beginning of 2007 takes the lead in announcing to eliminate incandescent lamp with legislation form comprehensively, successively there are tens countries and regions to issue incandescent lamp successively and eliminate plan.And three-primary-color compact-type fluorescent lamp, be commonly called as electricity-saving lamp, although the luminous energy output that 1/5 to 1/4 of ordinary incandescent lamp power consumption can reach same only need be expended, but also there is its drawback, as electricity-saving lamp starts slow, spectrum is discontinuous, simultaneously, electricity-saving lamp needs to add fluorescent RE powder, because fluorescent RE powder itself has radioactivity, electricity-saving lamp can produce ionising radiation (i.e. radioactive ray nuclear radiation), compares the uncertainty that electromagnetic radiation is encroached on human body, and excessive radioactive ray nuclear radiation more merits attention to harm.
Solid-state illumination is a kind of brand-new lighting engineering, utilize semiconductor chip as luminescent material, directly convert electrical energy into luminous energy, it is different from the tricolor powder luminescence that is luminous and electricity-saving lamp of the tungsten filament of incandescent lamp, semiconductor light-emitting-diode (LED) adopts electroluminescence, and photoelectric transformation efficiency is higher.Solid-state illumination has the features such as energy-saving and environmental protection, life-span be long, non-maintaining, easy to control.
The current main force's application of solid state illumination technology remains energy-conservation replacement, as factories and miness storage illumination, commercial lighting, road lighting and view brightening etc.In such applications, having many is scenes of demand high-power illumination, and great power LED luminous component, because its caloric value is large, often adopt the very large aluminium section bar heat radiation of volume.This passive radiating mode is the most conventional at present.
But above-mentioned passive heat radiation mode brings the problem of following several respects:
1, large, the Heavy Weight of lamp body;
Also produce amount of heat while LED electrified light emitting, bring the rising of temperature, the going down of brightness and life-span thus.Application Engineers often design the radiator selecting external form larger, improve heat loss speed by the mode increasing area of dissipation.This situation just bringing the general more traditional lamp body of LED lamp bigger than normal.While external form amplification, the weight of lamp body self also increases greatly, and this point shows particularly evident in the large-power lamp and electric light source of more than 30W.
For comparatively common 60W bulkhead lamp capable, the luminous component of 60W bulkhead lamp capable generally adopts the high-power integration module (COB) of 50W.This module area is less, and caloric value is very large, usually adopts diameter 160mm, and the cylindrical aluminium section bar of height 100-110mm is its heat radiation, and radiator deadweight is generally more than 2 kilograms.Add external power supply and power pack, whole lamp weight about 3 kilograms.And the 200-250W electricity-saving lamp of equivalent brightness typically have a diameter from 120mm, length is 370mm, shortage in weight 1 kilogram.The design of existing LED high power light source really needs to improve as can be seen here.
2, profile or interface do not mate;
As previously mentioned, current LED bay light radiator is huge, heavier-weight, and furthermore driving power is external, and these factors cause LED bay light, and with light fixture, the form of non-light source occurs usually, and the mode of hook lifting must be adopted to install.Replace in engineering at bulkhead lamp capable, latter two in traditional lamp stand, reflection shield, E40 lamp socket are often removed and abandon, cause the huge wasting of resources.Visible, the problem that the LED high power light source meeting conventional light source profile and interface is high practicability is produced in design.
3, temperature rise, light decay, contradiction between life-span and cost;
Continue for bulkhead lamp capable, even if LED bay light on sale in the market have employed very large radiator, the surface temperature rise of whole lamp body has still reached 30-35 degree Celsius, the inner Jie Wenzegenggao of LED.In market competition, the method that some manufacturer demotes with radiator, reaches the object reducing costs and knock down price to promote product.Common radiator degradation normally two kinds of approach, adopt aluminium section bar inferior or reduce heat sink section bar size, these two kinds of ways all objectively reduce thermal capacity and the radiating efficiency of radiator, thus raised the joint temperature of whole lamp temperature rise and LED, and finally cause LED long-term work in too high temperature environment, accelerate light decay, shorten the life-span.
